I have created a search and filter form that filters posts on the basis of tags, date range, categories, Posts order, etc. I just saw an unwanted post in the search result that I have not posted and is not there when I search for posts in WordPress dashboard. My whole website is in English. This post is appearing out of nowhere in french. Neither I’m able to remove this. I think its a security bug in the plugin. Please have a look at the following link. This is a very crucial issue for my website.

Here you will not find that unknown post. Even I searched it in my WordPress dashboard. There is no such post. But if you search using https://focusmerit.com/all-in-one-current-affairs/ it will automatically appear on 15th may 2020. If you click on that post, I get a 404 page not found.
Please resolve this issue. It could a security bug in this plugin.
Eagerly waiting for your reply.
